In addition, gas is often present in coal series or oil and gas formations, and the field electric welding or cutting operation has a great safety risk. Meanwhile, the joint of the conduit and the drilling hole is blocked by using an anchoring agent only, and the like, the slurry leakage is serious, so that the grouting quality, the rock-soil body reinforcing effect or the water plugging effect cannot meet the design requirements, and simultaneously, the great waste is caused.
The prior technical scheme has the following defects:
1. and (3) adopting a glass fiber bag layer to block the gap between the 42mm guide pipe and the grouting guide pipe: the pressure of grouting is 0.3-0.5 Mpa, so the expected value of the pressure of grouting can not be reached, and the reinforcement can not be effectively realized.
2. Grouting by using a sleeve valve pipe with a grout stop plug: because of adopting special rubber buffer, so the cycle of slip casting is longer, the cost is higher.
3. Deep hole grouting by adopting a retreating method: under the condition that no grout stopping measure is adopted, grout overflows when being close to the orifice of the deep hole, unnecessary waste is caused, and the grout stopping effect at the position close to the orifice is poor.
Chinese patent CN213144486U discloses a grouting plugging device for treating leakage water in water-rich sandy soil layer of subway tunnel, which comprises a plugging support box, wherein the middle part of the plugging support box is respectively fixed with a first grouting pipe and a second grouting pipe in a through-inserting manner, one end of the top of the first grouting pipe, which is positioned above the plugging support box, is fixed with an original glue grouting storage tank in an inserting manner, one end of the top of the second grouting pipe, which is positioned above the plugging support box, is fixed with a hardener grouting storage tank in an inserting manner, double liquid pumps are installed on the first grouting pipe and the second grouting pipe, the bottoms of the first grouting pipe and the second grouting pipe, which are positioned below the plugging support box, are connected with a grouting sleeve in an inserting manner, a grouting sleeve head is installed at the bottom of the grouting sleeve, a bidirectional screw is horizontally fixed in the plugging support box, a movable sliding sleeve is screwed on the outer wall of opposite threads at the left side and the right side of the bidirectional screw, a movable support plate is fixed at the bottom of the movable sliding sleeve, a fixed pressure frame is fixed at the top of the plugging support box, fixed pressure handles are symmetrically fixed at the left side wall and the right side wall of the fixed pressure frame, and the fixed pressure handles are not used for solving the problems of high grouting effect, such as high grouting effect, high strengthening time and high cost of easy-prone place in sandy soil layer.
